Gale Hawthorne frantically searched for her face among the survivors in woods. Only hours before, District 12 had been bombed by the Capitol. Gale did his best to try to get as many people out as he could, but everything had happened so fast that by the time he got there the house was completely consumed by flames. So he ran and prayed she got out and was smart enough to run into the woods.
He walked around searching for her face and praying she was alive. He swore to himself that if he found her, he would tell her how he felt. He would tell her that she's the prettiest girl in all of District 12 and that he loves her, for being there when Katniss couldn't, for being the only one who doesn't take his crap and knows how to make him feel better and all the little things. He would tell her that he's sorry for all the crap he's put her through and that it's not Katniss he wants but, her. He would kiss her and make up for all the times they almost did. Gale wasn't good with putting his feelings into words but he would find the words for her because she's different.
As he looked for her among the survivors all he saw was grey eyes and brown hair. There was no girl with silky blonde hair, bright blue eyes and a pretty dress that always made him smile to himself. As he looked among the last of the survivors he realized she wasn't here but dead.
In that moment he realized he would always love her but never get the chance to tell her. And in that moment he decided he would make the Capitol pay for taking the girl with strawberries away from him. He would avenge her, the girl who would always have his heart and he swore he would make them pay for killing her. For killing Madge.
